Hot tip: How to always get a high interest rate
A lot of high interest savings accounts offer special bonus introductory rates for the first few months only. This is a way for the bank to entice you to open an account. For example, the Rabobank High Interest Savings Account offers a competitive 1.35% p.a. for the first 4 months, which then drops down to the standard variable rate of 0.25% p.a..
So you could open this account to get the high rate, and then after the introductory period ends, you can move your savings into another account with a different bank to take advantage of their high introductory rate. Rinse and repeat to ensure you're always getting a high rate. Just remember, these offers are for new customers only so you can only open each account and get the high rate once.
